Hi,

I did as you suggested, disabling sendfile in apache removes the problem
tho didnt found any patches whitch would apply
(delta-sendfile-fix02/03 are for development version i think, and 04 made it
even worse)

also that made me to do some testing and got the 2.6.18.1 + lustre 1.5.95 +
vs 2.0.2.2-rc3 working,
but hit the same problem again (and another one thats im going to post
below)

now apache drops connection after 65207 bytes
(tested form inside and outside of the vserver running apache like beafore)

thing is that older version of vs running on 2.6.15 is doing fine, only
diffrence is that its not running lustre,
- files are stored on remote pc in both cases - so is it a possibility that
lustre is causing that ?

also :

when i start a jabber-gg transport inside a vserver i get:

[ 2388.382245] BUG: warning at kernel/pid.c:270/pid_task()

its popping up each time i start the service

TIA
